A coated article for use in separation of hydrogen from hydrogen containing gas or gas mixture comprises a refractory base material (2) with at least two flat surfaces (one of which is shown at 8), a hole (4) being formed passing through the base material (2) at one side, a grooved maze (6) being provided which extends from the hole (4) to the other side of the base material (2) and the maze (6) being coated with a hydrogen permeable membrane (14). A plurality of such coated articles can be stacked back to front, so that the outlet of one article is adjacent to the inlet of the neighbouring article. Such an arrangement, when located inside a closed furnace chamber, provides an apparatus for the separation of hydrogen from oxygen derived from the thermal dissociation of water vapour. <IMAGE> |
